InstallGear 12 Gauge AWG 30ft Speaker Wire True Spec and Soft Touch Cable - Speaker Wire 12 Gauge - Red/Black (Great Use for Car Speakers Stereos, Home Theater Speakers, Surround Sound, Radio)

These are true to their specifications of being Copper Clad Aluminum Conductors. This electrical wire conductor comprises of an inner aluminium core and outer copper cladding. Using CCA makes them economical to make (Core is aluminium rather than pure copper which is crazy expensive) with minimal losses. BTW as described, These are multi-stranded and of 12 AWG Gauge with Red/Black colors for easy Polarity Identification. Yes! even speakers have polarity and must be wired correctly both at speaker terminals and the gauge is correct size to fit inside Banana Plugs without having to cut extra strands.The 30-feet spool of wire does remain flexible after unrolling for easy routing especially inside tight spaced side panels with multiple bends. The Jacket is little softer than expected, easy to strip/peel but that also means it might get easily bruised in some applications. On the plus side, The resistance is low and good conductivity to the speakers even for the entire 30 feet. Low resistance = Good connection to speakers = more true Amps to the speaker = Good sound. That pretty much sums up the equation.For the asking price I think this is certainly worthy of five stars!

Used for my rear Focal speakers and no issues. Insulation on the wire is thick and I highly doubt any EMI would ever be an issue.

For the price it’s good quality

Worked well , perfect size and good quality

Color coded makes it super easy to connect source to speakers without any confusion of crossed polarity. Sound nice and does as advertised. Amazon delivered when promised. No complaints. Would recommend.

Nice insulation quality, wire as advertised. Very flexible.

Works good and looks good .

Good price, and plenty of length. This is for a surround sound. It's a good quality too.
